HTTP is dead, long live HTTP! 20 years ago, HTTP/1.1 was born and it has served us well. But a lot has changed since the time a single request was often enough to display a web page. Nowadays, web applications need lots of external resources, forcing us into hacky territory. We can do better! HTTP/2 is here and you can and should use it. No more domain sharding, resource bundling, convoluted hacks. Instead, you get much better performance and security with less work than before. This talk focuses on HTTP's history and its new features: multiplexing, header compression, server push and more! About Piet van Dongen By day, Piet is a software engineer at Luminis, where he keeps himself busy doing the whole full stack thing. By night, he sleeps. The rest of the time, he mostly entertains his kids, wife and vacuum cleaner, sometimes locking himself in the bathroom to read his Twitter feed or a book.

Presented by Nicki Bleiel at Documentation and Training LIfe Sciences, June 23-26, 2008 in Indianapolis. Documentation deliverables have evolved beyond manuals and online help in recent years, and with the emergence of Web 2.0, things are changing faster than ever. Technical communicators have many more options to enhance the user experience, and developing many of them provide the opportunity to work with other departments to find a more holistic approach to content development and delivery. But there is no one-size-fits-all set of solutions. This workshop will review the types of analysis you need to do to determine which deliverables are right for your project, your customer, and your company. Other factors that can’t be ignored, such as translation needs, staff/time constraints, file size limitations, corporate image and control, and proprietary concerns will also be discussed, including: Analyzing the Product * Intended audience; delivery method (desktop, web application, etc.); competitor offerings; software development methodology. The UI as part of the Help system. Product Management expectations. Identifying User Wants and Needs * Preferences and expectations for information; work environment; knowledge and experience levels. Ascertaining Internal Needs and Opportunities * Working with Training, Support, and Marketing to reduce duplication and provide the user with consistent, useful information. * Finding ways to incorporate information from other departments to improve documentation. Accessing Deliverable Options * What is the optimum mix for the product? * The traditional: online help, manuals, embedded help, job aids, forums, web sites, technical support knowledgebases. * Emerging trends: wikis, blogs, RSS feeds, software demonstrations, podcasts, and other collaborative tools. They can supplement and/or enhance the traditional. Or, they may be a better fit for internal knowledge management or marketing use. Optimizing the Library * Single-sourcing; best practices for structuring information; continuous publishing

Retrieval augmented generation (RAG) is the most popular style of large language model application to emerge from 2023. The most basic style of RAG works by vectorizing your data and injecting it into a vector database like Milvus for retrieval to augment the text output generated by an LLM. This is just the beginning. One of the ways that we can extend RAG, and extend AI, is through multilingual use cases. Typical RAG is done in English using embedding models that are trained in English. In this talk, we’ll explore how RAG could work in languages other than English. We’ll explore French, Chinese, and Polish.

Dubai, often portrayed as a shimmering oasis in the desert, faces its own set of challenges, including the occasional threat of flooding. Despite its reputation for opulence and modernity, the emirate is not immune to the forces of nature. In recent years, Dubai has experienced sporadic but significant floods, testing the resilience of its infrastructure and communities. Among the critical lifelines in this bustling metropolis is the Dubai International Airport, a bustling hub that connects the city to the world. This article explores the intersection of Dubai flood events and the resilience demonstrated by the Dubai International Airport in the face of such challenges.

Webinar Recording: https://www.panagenda.com/webinars/why-teams-call-analytics-is-critical-to-your-entire-business Nothing is as frustrating and noticeable as being in an important call and being unable to see or hear the other person. Not surprising then, that issues with Teams calls are among the most common problems users call their helpdesk for. Having in depth insight into everything relevant going on at the user’s device, local network, ISP and Microsoft itself during the call is crucial for good Microsoft Teams Call quality support. To ensure a quick and adequate solution and to ensure your users get the most out of their Microsoft 365. But did you know that ‘bad calls’ are also an excellent indicator of other problems arising? Precisely because it is so noticeable!? Like the canary in the mine, bad calls can be early indicators of problems. Problems that might otherwise not have been noticed for a while but can have a big impact on productivity and satisfaction. Join this session by Christoph Adler to learn how true Microsoft Teams call quality analytics helped other organizations troubleshoot bad calls and identify and fix problems that impacted Teams calls or the use of Microsoft365 in general. See what it can do to keep your users happy and productive! In this session we will cover - Why CQD data alone is not enough to troubleshoot call problems - The importance of attributing call problems to the right call participant - What call quality analytics can do to help you quickly find, fix-, and prevent problems - Why having retrospective detailed insights matters - Real life examples of how others have used Microsoft Teams call quality monitoring to problem shoot problems with their ISP, network, device health and more.

The microservices honeymoon is over. When starting a new project or revamping a legacy monolith, teams started looking for alternatives to microservices. The Modular Monolith, or 'Modulith', is an architecture that reaps the benefits of (vertical) functional decoupling without the high costs associated with separate deployments. This talk will delve into the advantages and challenges of this progressive architecture, beginning with exploring the concept of a 'module', its internal structure, public API, and inter-module communication patterns. Supported by spring-modulith, the talk provides practical guidance on addressing the main challenges of a Modultith Architecture: finding and guarding module boundaries, data decoupling, and integration module-testing. You should not miss this talk if you are a software architect or tech lead seeking practical, scalable solutions. About the author With two decades of experience, Victor is a Java Champion working as a trainer for top companies in Europe. Five thousands developers in 120 companies attended his workshops, so he gets to debate every week the challenges that various projects struggle with. In return, Victor summarizes key points from these workshops in conference talks and online meetups for the European Software Crafters, the world’s largest developer community around architecture, refactoring, and testing. Discover how Victor can help you on victorrentea.ro : company training catalog, consultancy and YouTube playlists.
